Introduction
Dreame presents two generations of high-end robot vacuum cleaners that compete directly with the Mova P50 Pro Ultra, a model belonging to the same manufacturer's second brand. The Dreame L40 Ultra arrived in 2024, whilst the Dreame L40s Pro Ultra and the Mova P50 Pro Ultra were launched in 2025, incorporating technical improvements over the previous model.
All three units feature a multifunction base that washes and dries the mops, laser navigation system with dual camera, and advanced mopping capabilities. They are designed for homes seeking complete automation of floor maintenance, especially useful in households with pets thanks to their anti-tangle systems and brush elevation.
Power and Suction
The most notable difference in suction power is found between generations. The Dreame L40 Ultra offers 11,000 Pa, a respectable figure for 2024 that handles hard floors and medium-pile carpets without problems. The 2025 models make a considerable leap to 19,000 Pa, which translates into greater capacity for thick carpets and ingrained dirt.
The main brushing system marks another important distinction. The L40 Ultra and the Mova P50 Pro Ultra maintain the TriCut 3.0, which combines bristles with blades to cut tangled hair. The Dreame L40s Pro Ultra incorporates a dual brush that further reduces tangles, especially useful in homes with several pets. All three models raise the main brush during mopping to avoid contaminating the water.
As for the side brush, all three units share identical features: extension to improve corner cleaning, elevation during mopping, and anti-tangle technology. This configuration proves practical for keeping the brush free from long pet hair and human hair.
Mopping
The mopping system is practically identical across all three models. All use two rotating mops with side extension capability and the Roboswing system, which allows the robot to perform movements to introduce the mops under furniture and overhangs. Mop elevation reaches 10.5 mm in all cases, sufficient to transit over thin carpets without wetting them.
All three can automatically detach the mops at the base when only vacuuming is needed, avoiding having to remove them manually. Dirt detection works on both the mops and the floor, allowing the robot to identify areas requiring additional scrubbing. The water used for mopping is cold on all models.
Navigation System
Navigation is based on LiDAR turret combined with dual front camera and 3D laser sensor on all three units. All recognise pets, detect curtains to avoid tangles, and feature LED for night vision. Remote camera access allows supervision of cleaning from the mobile.
Obstacle recognition capability shows clear evolution. The Dreame L40 Ultra identifies 100 different objects, the Mova P50 Pro Ultra rises to 160, and the Dreame L40s Pro Ultra reaches 180. In practice, this means the most recent Dreame model has greater precision for avoiding cables, small toys, or slippers, reducing manual interventions.
The L40 Ultra's processor uses AI Sage 11.0, although we don't have information about the specific chip in the 2025 models. All three incorporate CleanGenius intelligent cleaning and AI-powered stain recognition.
Autonomy and Battery
All three robots mount 5,200 mAh batteries, but energy management varies. The Dreame L40 Ultra achieves 194 minutes of autonomy, the Mova P50 Pro Ultra reaches 210 minutes, and the Dreame L40s Pro Ultra sits at the top with 220 minutes. This difference can be explained by optimisations in power management software and suction motor efficiency.
For homes up to 200 square metres, any of the three completes cleaning without intermediate recharges. In larger houses, the additional minutes of the L40s Pro Ultra can make the difference between one or two charging sessions.
Smart Functions
The ability to overcome obstacles presents significant differences. The Dreame L40 Ultra and the Mova P50 Pro Ultra overcome steps up to 22 mm, height sufficient for most transitions between rooms and thick carpets. The Dreame L40s Pro Ultra incorporates an improved system that allows it to climb simple steps, although the exact height is not specified. This expands its versatility in homes with more pronounced level changes.
All three models include their own voice assistant and compatibility with Alexa and Google Home, facilitating control by voice commands without needing to open the app.
Multifunction Cleaning Base
All three bases perform auto-emptying of the dust bin, washing and drying of mops. The dust bag has a capacity of 3.2 litres in all cases. Mop washing is carried out with hot water and drying with hot air, features that help eliminate bacteria and prevent bad odours.
Self-cleaning of the washing tray marks a technical difference. The Dreame L40 Ultra incorporates second generation of this system, whilst the L40s Pro Ultra and the Mova P50 Pro Ultra feature third generation, which improves the elimination of residue accumulated in the base itself.
The clean and dirty water tanks are identical on both Dreame models: 4.5 and 4 litres respectively. The Mova P50 Pro Ultra slightly reduces these capacities to 4 and 3.5 litres. In practice, this difference barely affects medium-sized homes, although in very large houses it may involve an additional refill every several cleans.
Both Dreame models offer an optional plumbing connection kit, which is purchased separately and allows automation of water filling and emptying. The Mova P50 Pro Ultra does not have this option. All three include a detergent tank for adding cleaning product during mop washing.
Dimensions
All three robots share identical dimensions: 350 mm diameter and 103.8 mm height. This measurement allows them to access under most standard furniture, such as sofas and beds with legs of 11-12 cm or more.
The differences appear in the bases. Both Dreame models measure 340 mm wide, 590.5 mm high, and 456.7 mm deep. The Mova P50 Pro Ultra presents a different configuration: 420 mm wide, 470 mm high, and 458 mm deep. In summary, the Mova base is wider and lower, whilst the Dreame bases are narrower and taller. It's advisable to measure the available space before deciding, especially if you plan to locate the base in a specific gap.
Real-World Experience
For households with pets, the Dreame L40s Pro Ultra offers clear advantages: greater suction power, dual anti-tangle brush, and better obstacle recognition. This translates into fewer interventions to free hair from the brush and greater effectiveness collecting dog or cat hair from carpets.
In large homes, the autonomy of the L40s Pro Ultra (220 minutes) and its ability to overcome simple steps facilitate cleaning of entire floors without interruptions. The Mova P50 Pro Ultra sits at a midpoint with 210 minutes, whilst the L40 Ultra may require recharging on surfaces exceeding 180-200 square metres.
The third generation of tray self-cleaning in the 2025 models reduces manual maintenance of the base. This proves especially useful if mopping frequently, as the accumulation of residue in the tray is lower.
The plumbing connection kit available on the Dreame models (although purchased separately) may interest those seeking total automation and who don't want to deal with refilling or emptying tanks. The Mova doesn't offer this possibility.
Conclusion: Which to Choose?
Choose the Dreame L40 Ultra if you're looking for a complete robot with multifunction base at a more competitive price than the 2025 models. Its 11,000 Pa is sufficient for most homes without very thick carpets, and it features all the essential functions: hot water washing, hot air drying, mop extension, and intelligent navigation. Ideal for homes up to 150-180 square metres without pronounced level changes.
Choose the Dreame L40s Pro Ultra if you need maximum suction power (19,000 Pa), the highest autonomy of the group (220 minutes), and the most advanced obstacle recognition (180 objects). The dual brush and ability to overcome simple steps make it the best option for large houses with pets, thick carpets, and multiple rooms. The third generation of tray self-cleaning reduces maintenance. Advisable if you prioritise performance over price.
Choose the Mova P50 Pro Ultra if you're looking for 2025 specifications (19,000 Pa, third generation self-cleaning, 160 recognised obstacles) but prefer a base with a wider and lower configuration that may fit better in certain spaces. Bear in mind that it doesn't offer a plumbing connection kit and the water tanks are slightly smaller. Good alternative for medium-to-large homes without need for extreme water automation.
